[cost\_intel] Fine-tuning break-even volume is 50k\+ monthly requests with stable schema for 6\+ months

Use fine-tuning only when monthly volume exceeds 50,000 requests, output schema is stable for >6 months, and latency requirements are strict \(<200ms\); otherwise use 3-5 shot dynamic example selection with base models.

Journey Context:
Fine-tuning carries fixed costs \($500-2000 training \+ validation\) and reduces per-token costs 40-60%. Below 50k requests/month, the fixed cost dominates; above 100k, savings compound. Few-shot adds 30% latency and variable token costs. Signature of misfit: training on <10k examples \(overfitting\) or schemas changing monthly \(retraining costs\). Fine-tuning excels on proprietary formats with strict latency SLAs.
